NON-REFILLABLE BOTTLE.

Specification of Letters Patent.

Patented Jan. 3, 1911.

Application filed May 29, 1910. Serial No. 562,478.

To all whom it may concern:

Be it known that I, Josnri-i C. humans, a subject of the King of GreatBritain, residing at Jamestown, in the county of Chautauqua and State ofNew York, have invented new and useful Imprm'ements in Non-RefillableBottles, of which the following is a specification.

This invention relates to bottles and other like containers. andparticularly to stoppers therefor, the object being to provide a novelconstruction of stopper which will prevent or deter to a maximum extentattempts to refill the bottle after the original contents have beendischarged.

The invention consists of the features of construction. combination andarrangement of parts, hereinafter fully described and claimed, referencebeing had to the accom panying drawing, in which Figure 1 is a verticaltransverse section through the neck of a bottle embodying my inventiontaken substantially on the line 1-1 of Fig. 2. Fig. 2 is a similarsection on the line 2-2 of Fig. 1. Fig. 3 is a hori zontal section takenon the line 33 of Fig. 1. Fig. +t is a horizontal section taken on theline of Fig. 2. Fig. 5 is a vertical section taken on the line of Fig.1, showing the sliding valve or cut-off in normal or closed position. F6 is a view similar to Fig. showing the valve or out off in the openposition it assumes when the bottle is tilted.

Referring to the drawing, 1 designates the neck of a bottle or containermade of glass or other suitable material which neck is provided at apoint below its rim with an annular offset forming a correspondinglyshaped channel 2 communicating with the interior of the neck.

A stopper 3 of glass or other material is provided to close the neck,and is provided at its upper end with a lug or finger piece 4: by whichit may be conveniently manipu lated during the operation of insertingit. As shown, the stopper comprises a plug adapted to fit the neck andprovided at one side of its vertical center with a discharge channel orpassage 5 extending entirely therethrough and having a lower flaring end6 facilitating the entrance of the liquid. Communicating with thispassage at a point intermediate of its length is an inclined ordiagonally arranged chamber 7, having its upper end facing the side ofthe bottle whlch is designed to face downwardly when the bottle istilted for the discharge of its contents.

Fitted to slide within the chamber 7 is a valve or cut-off 8, of lesslength than said chamber but corresponding in depth and width therewith,said valve being provided at one end with an aperture 9 adapted toregister with the passage lVhen the bot tle is in an erect position. thevalve closes the passage 5 and occupies, through the force of gravity,its lowest position in the chamber 7. hen, however, the bottle is tiltedfor the discharge of a portion of its contents, the valve slides in theopposite direction and its port 9 is brought into register with thepassage 5 to permit inflow of air and outflow of the liquid.

Through the described operation of the sliding valve, it will beapparent that when the bottle is in normal position or inverted, thevalve will close the passage 5 and thus prevent either inlet or exit ofliquid, and that the valve will move to a position to open the passageonly when the bottle is tilted to a prescribed position. Formed withinthe body of the plug is a narrow transverse cavity 10 having a roundedtop wall and communicating atits base with a slot 11, which slot is ofgreater width than the cavity but of less length than the same. Formedin the sides of the plug and communicatingwith the end of the baseportions of the cavity are preferably angular openings 12 to receivesliding locking dogs 13, which project therethrough into the channel 2and thus lock the stopper a ainst removal within the neck. These dogscomprise blocks of glass or other suitable material in which areembedded the ends of a substantially semi-circular bowed spring 14;which bears normally against the curved wall of the cavity and isprovided with a central coil 15, the arms of said spring being normallyforced apart by the coil to hold the dogs or blocks projected. By thismeans casual retraction of the dogs is prevented, so that the stoppercan not be removed from the neck without fracturing or otherwisemutilating the same to such an extent as to give visual evidence to thefact that the bottle has been tampered with.

The slot 11 is provided for the insertion of the dogs 13 and spring 14.In applying them, one end of the spring and the dog carried thereby areinserted at an angle upwardly through the slot into the cavity 10,

bv the tinoers until the lower portions there- 1 of enter the neck, inwhich position they will remain as the plug is forced downward untilthey come opposite the channel Zinto which the will. be automaticallyprojected by the action of the spring. The finger piece iis provided forthe convenient manipulation of the stopper in insertingit.

A. stopper 5 is provided to close the top of the passage 5 duringstorage or t1.'ansporta tion Of the bottle.

From the foregoing; description, taken in connection with the drawing.the construction and mode of operation of my improved bottle closurewill be readily rnderstood and it will be seen that a type of closure isprovided which can be ine:tpensivel manufactured and which will preventor deter to a maximum degree attempts to refill the bottle.

Having thus described the invention, It claim 1. the combination with abottle, of a stopper adapted for insertion within the bot tle neck andprovided with means for locltinc; it: thereto, said stopper being formedwith a vertical discharge passage and an inclined chamber crossing saidpassage and opel'iing laterally tl'trough one side of said stopper, anda sliding valve arranged in said chamber and of less length than thesame, said valve having an outer longitudinally curved edge bearingagainst the adjacent side of the nec and. being provided at one end witha port to register with the passage when the bottle is tiltedto aprescribed position.

'lhe combination with a bottle. of a stopper comprising a plug adaptedto be locked within the bottle neck and having a valve controlleddischarge passage said stopper being formed with a cavity openingthrough its base and with. openings in its si communicating with thebase of the savitv, said cavity having a rounded top wall, dogs slidablein said openings and adapted to engage keepers in the neck of the bottleand a bowed spring disposed within the cavity and having its armsconnected with the dogs and its central portion arched to conform to andbearing against the rounded. top wall of the cavity and provided with acoil.

in testimony whereof I atlix my signature in presence of two witnesses.
